Runs were at a premium for Australia's ODI side prior to an upswing in form in 2019, with Aaron Finch's side winning back-to-back series away from home against India and Pakistan.

In a heartbeat, Australia has leapt back into the discussion to win the World Cup and defend their 2015 crown. Four years ago, Warner was an integral cog in Australia's run to the title, scoring 345 runs at 49.29 in eight appearances.

Coming into the 2019 tournament, Warner is Australia's form batsman right now. Make no mistake about it. Finch scored runs for fun against Pakistan, but that was a month ago.

Regardless, taking time off following the Newlands saga and getting back to his roots helped Warner refine himself, and find top form at the right time.

"I have had time off to work harder at my game," he said after Monday's match in Hyderabad.

"I put the bat down for 16 to 18 weeks and just worked hard on being the best father and husband. That has worked for me.

"I try and always do that around the team, be the funny man and prankster and try my best to give what is good for the team."

One question for Australian selectors is who opens in the World Cup. Since the 2015 tournament, Warner has scored 2296 runs at 56.00, Finch 2325 at 41.51 and Usman Khawaja 1224 runs at 47.07. The latter may get the tap on the shoulder, but Warner could make it an easy decision.
